SEYMOUR M. HERMANN, OF NEW YORK, N. Y.

SIZING COMPOUND.

No Drawing.

To all whom it may coiwemr Be it known that I, SEYMOUR M. HER- MANN, a citizen of the United States, and a resident of the city, county, and State of New York, have invented certain new and useful Improvements in Sizing Compounds, of which the following is a full, clear, and exact description.

The object of this invention is to produce ".20 that is treated with various reagents, and to 1 7k w/i which other materials are added, such as starch or glue. This compound is usually mixed with a suitable vehicle such as play or other earthy material, and then sometimes a solution of wax is added.

The purpose of the present invention is to provide a substitute for the materials that are mixed with this vehicle of clay and wax, or other materials, for producing a sizing compound.

My improved compound consists essentially of four ingredients, or three of these four ingredients. To these ingredients is also preferably added any suitable preservative material or compound, for the purpose of preventing the decomposition of the compound.

The invention broadly stated consists of a mixture of, first, a compound or material of a starchy nature, or preferably simply starc econd, I employ a solution of 'ffossfbf any desired character. Third, I a a um of suitable character. And the fourth component of my improved compound, is a soluble silicate. Instead of employing these our ingre ients, either the gum may be omitted and the other three Heater use the mgss cap be left opt and the other three employ eidf In regard to the first-mentioned ingredient of my compound, the starch used may be either what is known in the chemical industries as a dir s or else what is termed an inverted starch. For the direct starc Wou mention that almost any of the known or general substances Specification of Letters Patent.

of this character may be employed. It may be derived from corn, wheatgye, sweet potatoes or white potatoes. tapioca. sa o, rlce cassava beans or barle usually derived from tee plants, that is from their fruit, or from their root. But it is to be understood that this element may consist of a m ifie st or an inverted starch; such as would be produced of suitable chemical reagents, as acids alkalis, diastifor, pliastase, heat steam 113355 pressure, or Ky the action of heat 1n combination with these said reagents. And

under the term starch is also to be included dextrin. In regard to the second said component, the solution of moss can be of any of the mosses; Irish moss having been found very suitable or is purpose. The

third ingredient of my new compound may be any of the substances known in the chemical art as a um; and it is to be understood that this gum may be an exudation from a tree or plant, which is a gum produced by nature, or else it may be a synthetical gum,

that is, one produced artifically by certain chemical reagents. As an example of the latter may be mentioned the compound known as British um that is the resultant ofthe actlon on starch of a suitable chemical, such as an acid, or an alkali. This artificial compound has substantially all of the characteristics and properties of the gums produced in nature by the exudation from trees. used are um a osol, and um tra acanth, and the latter is preferablW results as any, and its cost being least. These three ingredients, or starch and either one of the others, the moss, or a gum,

are combined with a soluble silicate. I preferably employ a silicate of an aIEaline metal; a silicate of soda having been found to give very advantageous results.

It will therefore be understood that my improved compound preferably is formed of starch, solution of Irish moss and a sili; f soda, or other soluble silicate. EH:

cate o practically as good results are obtalned by a and a solution of silicate of so a. r

ese our in employ this compound mixed with a suitable vehicle or carrying compound, such as Such starc es are so by the reactlon 5 The two gums that I have most 90 mixture of starch, a um such as gum tra 'a- 1 starch Irish moss g m silicate of sdIdE-l is above stated, the general purpose is to b t ww cla and a solution of wax. But, it is the purpose of 11s inven ion 0 prepare as an article of manufacture for sale my said compound formed of the four recited ingreclients, or the mixture of certain three of the same. This will preferably be supplied to the trade to be mixed by them, only as and when required for use, with the said vehicle.

It is also preferable, especially when the compound is not desired for immediate use to add to the compound any suitable preservative that will prevent reaction between t e components, or any change in their nature. For instance: I may add carbolic acid dissolved in 1 ccr- I may emp oy a mild solution of or 1 or this purpose.

In regard to the preparation used, solutions of the moss, of the starch, and. of the silicate of soda may be one per cent. solutions. As to the relative proportions of the three ingredients, I may use five parts of the starch solution, one part of the gum (or of'the moss) and about six parts of the silicate of soda; that is, these twelve parts are added to about eighty-eight parts of the ve hicle. But where the gum and moss are both used, I would employ five parts of starch solution, one part of moss solution, one-half part of the gum, and six parts of the solution of the silicate of soda; these to be added to about eighty-eight parts of the vehicle.

It will be thus seen that the compound that I have produced is comparatively cheap to furnish, and easy to prepare. The gums, or the Irish moss, are obviously much cheaper than the casein now usually employed for this purpose.

Having thus described my invention, I claim as new and desire to secure by Letters Patent Copies of this patent may be obtained for 1. A sizing compound comprising starch, a gum, a' solution of moss, and a soluble silicate.

2. A sizing compound comprising starch, a gum, a solution of Irish moss, and a soluble' silicate.
